Francis has 18 eggs out of which 12 eggs were sold at 10% loss than the cost price. At what mark up should he sell the remaining eggs to cover his losses?

10%

15%

20%

Explanation:

Let 1 egg cost Rs 1.
Cost of 1 eggs = Rs 18.
Cost of 12 egg = Rs 12.
SP of 12 eggs = 12 –1.2 = 10.8
To cover the cost, he should sell remaining 6 eggs at 15 –10.8 = Rs 4.2
Profit = (1.2/6)×100 = 20%
